wrapping geo like Wrap3

Hey guys,

I guess many of you have seen this: Wrap3

Has anyone got an idea if this is possible with Houdini? If yes I'd be thankful for some pointers.

Cheers

Oli

I think you could do that with the RAY sop. You may need to resample the source or the target so they have the same number of points.

ray_sop is not able to do that I guess since it only projects points. Wrap3 actually "wraps" a mesh around another mesh.

Anyone else?

point clouds would better then ray sop....

*edit:
actually ray-sop and then point cloud look up works best.

the only save way would be unfold the geo in one 2d plane (pretty much uv unwrap) for boeth geo and match uppoint wih point clouds radius. to make it in vex it could a little tricky..... i 've never did it in houdini...

Seems like an advanced tool for me. I think it's not possible in Houdini, unless you'll write such solver from scratch using basic Houdini tools. You need to know algorithms behind this technology. Ray SOP basically does a raytrace. It is somewhat useful to conform meshes with almost identical shape, but it won't give you advanced results like transforming a base state of modeled hand into a gesture from scan. Same problem with point clouds.

This is very very good File! Thank you Petz. I did not know it is possible with Houdini.

thanks for that file petz! After looking at it I feel like I know nothing about Houdini :) Need to dig into all the nodes now! Thanks a bunch!

What exactly are you doing in CHOPs?

Cheers

New point positions based on the reference geo are being interpolated in CHOPS. Here is an example from years ago with similar functionality
